3d19b75147 adapter: add method to keep track of timestamps
Keep track of the timestamp and offset associated with the current head of the
adapter.

API: GstAdapter::gst_adapter_prev_timestamp()

605639a2bf adapter: optimize taking the headbuffer
When a are requested to take a buffer from the adapter that is exactly the
headbuffer, don't make a subbuffer of it but return that head buffer.

Add a unit-test for this new optimisation.

471bd93af5 adapter: remove dead assignment.
The value set to to_copy at that line is never used, and is overwritten
further down before being read.

b9b5877a51 gst/gstelement.c: Don't output the same debug statement twice.
Original commit message from CVS:
* gst/gstelement.c: (gst_element_get_state_func):
Don't output the same debug statement twice.
* libs/gst/base/gstadapter.c: (gst_adapter_try_to_merge_up),
(gst_adapter_peek), (gst_adapter_take_buffer):
Optimise the case where we have buffers at the head of the queue that
can be joined quickly (because they're contiguous sub-buffers) by
merging them together rather than copying data out into new memory.
* gst/parse/grammar.y:
* tests/check/pipelines/parse-launch.c:
Fix a leak in an error path for parse_launch, and add a check
for it to the testsuite.

* libs/gst/base/gstadapter.h:

(GST_START_TEST), (gst_adapter_suite):
* tests/examples/Makefile.am:
Do some optimisation work in GstAdapter to avoid copies in more cases.
It could still do slightly better by merging buffers when
gst_buffer_is_span_fast is true, but is already faster.
Also, avoid traversing a single-linked list to append each incoming
buffer inside the adapter.
Add simple test app that times the adapter behaviour in different
situations, and extend the unit test to check that bytes enter and
exit the adapter in their original order.

* gst/gstutils.h (GST_BOILERPLATE_FULL): Prototype instance_init
